Effective 19 September 2026. Wine Taster’s Handbook is operated by Premium Analysis Services LLC.
The short version: you can use this site without an account and without giving us anything. If you make an account, we store your email and the trips you save, and nothing else. Wineries can see how many people saved their listing, never which people.
The site is intended for people 21 and over. We do not knowingly collect information from anyone under 21. If you believe a minor has created an account, email us and we will delete it.
If you do not sign in: nothing that identifies you. Browsing the map, the directory and the region pages requires no account.
If you sign in: your email address, which is how the sign-in link reaches you, and whatever you save: wineries you bookmark, rooms you mark visited, itinerary picks, and saved handbooks including any notes you write in them. Notes are private to your account.
If you claim a winery listing: the contact details you submit with the claim, so we can verify you are connected to that business.
Automatically: our hosting provider logs standard request information such as IP address and browser type, for security and to keep the site running. We do not use it to build a profile of you.
We do not sell or share your personal information, as those terms are defined under California law. We do not run advertising on the site, and there are no advertising or cross-site tracking cookies.
Some browsers send a Do Not Track signal. There is no common standard for responding to it. We do not track you across other websites, so the signal does not change what we do. We do not allow third parties to collect personal information about your activity across other sites through this one.
We show wineries how their own listing performs: how many times it was viewed, saved, or added to a planned trip over a period. These are counts only.
Wineries never see who you are. They do not receive your email address, your name, your other saved wineries, your itineraries, or anything you write in a handbook note. We do not report a figure derived from fewer than five people, so no winery can work out that a particular person saved its listing.
Accounts and saved data are stored with Supabase, our database provider. The site is served through Cloudflare. Maps are rendered by Mapbox and OpenStreetMap, which receive the map requests your browser makes. If you choose to sign in with Google, Google handles that step. Each acts as a processor or an independent controller under its own terms.
A sign-in session is kept in your browser so you stay signed in between visits. Signing out clears it. That is the only cookie the site sets itself.
We keep your account data while your account is open. If you ask us to delete it, we remove it within 30 days, except anything we have to keep to meet a legal obligation. Routine backups are overwritten on a rolling basis.
Access rules at the database mean your rows are readable only by your own account, and the site is served over HTTPS. No system is perfectly secure. If a breach affects your personal information we will notify you as California law requires.
You can ask for a copy of what we hold about you, ask us to correct it, or ask us to delete your account and everything attached to it. Email hello@winetastershandbook.com and we will action it. We will not treat you differently for asking. Deleting your account removes your saved wineries, trips, handbooks and notes.
California residents may also ask once a year what personal information we shared with third parties for their own direct marketing purposes. We do not share information for that purpose, and the answer will say so.
Listing information about businesses, such as addresses, hours and tasting fees, is business information compiled from public sources, not personal data. If you are a winery and want a detail corrected or removed, email hello@winetastershandbook.com.
If this policy changes materially, the effective date at the top of this page changes with it. Questions: hello@winetastershandbook.com.
